Reentry - A Space Flight Simulator - wilhelmsenstudios

The 0.84 is a dedicated update for the Lunar Module and its Environmental Control System. In addition, a lot of blocking fixes and issues has been resolved in Mercury, Gemini and Apollo.

First of all, thank you to those who were part of the AF-1 mission to test these bits! Like usual, testing will still go on and corrections will be made as things are discovered.

Lunar Module Environmental Control System (LM ECS)
The first iteration of the Lunar Module ECS has been added. This is a huge network of systems working together. It contains the Atmosphere Revitalization Section (ARS), the Oxygen Supply and Cabin Pressure Control Section (OSCPCS), the Water Management System (WMS) and the Heat Transport System (HTS). As with the CSM ECS, this is not the complete implementation but a good start and covers many of the basic procedures and operational requirements.

With the LM ECS comes a bunch of new checklists to monitor the LM ECS, how to depressurize and repressurize the cabin and redundancy checks.

A new Lunar Module Academy lesson has been added that will teach you the basics of it and covers some of the new checklists.


The following diagrams shows a good overview of most of the additions you will see in the LM DPS.
The first system is the ARS. It will control the atmosphere in the cabin and the suits. A CO2 filter replacement system similar to what we have in the CSM has also been added.


The OSCPCS provides oxygen from the descent and ascent stage for use in the ECS, such as for the ARS above.


The WMS is controlling the water from the descent and ascent stages. It is needed for temperature control and consuming.


The HTS is responsible for heat control of the equipment using liquid coolant.


All of these systems play together as the LM ECS. Operating these might seem hard, but most is automatic as long as it's configured correctly based on mission need.

Lunar Stay Operations
The update also adds new procedures needed for Lunar Stay operations. This is tied with the LM ECS and covers the procedures needed to configure the Lunar Module correctly as it stands on the Moon. At this phase, the spacecraft is transformed into a home where two astronauts will live. Guidance systems and so on are not needed, and the things that consumes unnecessary power is shut down, and the primary power source is changed.

Multiple new checklists has been added to cover the Lunar Stay operations, and a dedicated Lunar Module Academy lesson has been added to explain them.

The End of a Decade campaign receives a Lunar EVA
Added an EVA to the Mission 5 of the Lunar Module Campaign (IV). It simply extends the mission and follows the procedures to do an EVA. The Academy lesson should be completed before attempting.


Crew Management
Added a CREW MANAGEMENT page to the CREW MEMBERS feature accessed from the C-menu. Used to move crew between the CSM and LM. An override exists that you can use for old save states, it will let you position crew without being docked and open hatch.

In addition, the crew members names can be changed to the names you wish. They will be set based on mission parameters from the Mission Definition file initially, but can be modified in-game.


Reversed Lunar Module P16 + lights
Made some general fixes on LM Panel 11 and Panel 16 such as more realistic circuit breakers lights, and reversed the P16 layout to match the realistic layout.

Here is the new P11:


Here is the new P16:


Here is the LM interior as a "whole":


New Apollo scenario: Coasting Home
This scenario will take place as the CSM has left the Moon with a TEI-burn. It is on a trajectory between Earth and the Moon, with about 50 hours of traveltime before reentry. The crew must correct the entry trajectory, prepare for entry, and land.

MOCR - Apollo Mission Control

Added one of the two LM TELMU/ECS channels (ch 36) to monitor and debug the LM ECS. This enriches the TELMU role of MOCR with all the data needed to monitor the LM ECS, and make actions.


Added the Mission Control headsets to Mercury Control Center and MOCR sessions, and fixed the mouths to prevent them from being open all the time. Thanks a lot to Paolo Mangili for simplifying his 3D model of the headset and providing it to the Reentry project!


MOCR stability changes and server selection,
A lot has been done to improve the stability on MOCR sessions. MOCR is currently only in alpha testing phase 1, where the network logic and stability is the primary development area.
I have also added server selection dropdown that lets the host select where the server will be created, or where you wish to connect when in MOCR. This improves ping and stability as the region (should be) is closer to the host. If the host is in Seattle for example, the game could be created on the USA, West region.

A new Connect button has been added next to the dropdown in the MOCR room. This button also works as a "RECONNECT" so hopefully you wont have to go back to the main menu again to reconnect to sessions.

The reconnect button has also been made functional.

Issues and corrections
Gemini
- Fix for the Agena/Encoder code 220 for undocking and rigidize.

Command Module
- Fixed stability issues on the CSM ECS, and corrected some vent valves.
- Realistic GDC Align procedures can now be used
- Changed the CSM entry academy with steps to enable the batteries to power the CSM

Lunar Module
- Fixed the overpowered Lunar Module PGNS issue

Mercury Control Center
- Fixed the panels where the text had become invisible

Typos & Misc
- Merged typo and issue pull requests from GitHub for Checklists and Missions
- VR Laser Pointer logging for gathering data on cases where the laser pointer goes through the UI

Looking ahead. short term:
In the next updates I will be looking at improving the Gemini procedures to improve its realism. A PR has been created on GitHub that contains a lot of refined checklists and procedures that will be merged in. Slight changes to the Gemini Academy and missions will be made to reflect this. The Mercury ECS will also get a slight overhaul and updates. This is planned as the 0.85 update.

Then I will add a Lunar Module DPS Burn Planner used for DPS burns such as when performing a DOI. Typically, unless done manually, the CSM SPS has been used for any major orbital changes before the Lunar Landing. In Apollo 11, the LOI was done by the CSM, while the DPS did the rest. With the DPS burn planner, this can be done by the DPS. The procedures will be similar to an SPS burn where the planner is first used, then the P30 and P40 to execute the burn. P52 opt 1 will also be added for better and more precise burns.

As we are closing in on the 0.9 era of Reentry, multi-language support will be in focus, as well as integration with different services. This will lead us into 1.0 where once again systems will be in focus so that more historical missions can be created. Historical missions require a lot of systems to be in place and aligned to create. We will also start to focus more on multiplayer modes, and VR.
In addition, I have received many requests (some that has been added in recent updates), and I would like to figure out the feasibility of adding them such as Apollo Space EVAs, Saturn IB & Skylab, the Apollo Lunar Surface Experiments Package (ALSEP) for Lunar EVAs, new spacecrafts such as Vostok as a DLC, etc.

We will see what the future holds, but my point is that the 1.0 milestone will be about getting a solid fundament to build the future of Reentry on, while the journey to 2.0 will hold a lot of exciting things! :)

That's it for now, thanks again for all your feedback, input and suggestions!

Are you familiar with the Lunar Module? Do you like to test and play around with a Lunar Module that is glued together with duct tape?

The Alpha Floor - 1 mission is for those who want to try out the latest (untested) bits before the 0.84 release is out. The intent is to get some proper feedback and testing on the bits through alpha-testing before they are released to the Early Access public branch.

Alpha testing has been going on for a good while, but this is the first time I try to set it together as a collaborative effort to test. We have been doing similar missions in the Test Pilot program with good success. The main testing platform is on the official Reentry Discord server, so you will need to be part of this community as most of the discussions, iterations and such happens there. You can join here: http://discord.gg/reentrygame

So what's the plan?
The main part of this update is the first iteration of the Lunar Module ECS, and CSM GDC gyro drifting.

The LM ECS is a huge system and contains the Atmosphere Revitalization Section (ARS), the Oxygen Supply and Cabin Pressure Control Section (OSCPCS), the Water Management System (WMS) and the Heat Transport System (HTS). This is not the complete implementation but a good start and covers many of the basic procedures and operation requirements. The depressurization/repressurization and venting time has been multiplied to make testing a bit faster for this first iteration.

New checklists related to the LM ECS and the LM Lunar Stay Operations + EVA has been added too.
The academy will take you through most of the changes, and will be the main focus of this first AF-1 mission.


FLIGHT PLAN
1) Test the Lunar Module Academy lesson 11: ECS
2) Test the Lunar Module Academy lesson 13: LUNAR STAY & EVA
3) Test the MOCR LM ECS display and monitor its data in a session (requires a live session*)
4) Monitor CSM IMU vs GDC on the MOCR consoles (requires a live session*)

*live sessions can be set up when needed, just request one on Discord and we will try to make it happen

If you decide to join in on testing, join the Discord server if you are not yet there, and switch to the alpha floor branch as explained here: https://steamcommunity.com/app/882140/discussions/0/3118160027737663624/
This page will also contain all the details for each af-build, so if you are curious of all the 0.84 updates, check here.

If you decide to join (it's not for everyone) keep in mind that you do not need to test every step. do one, then report, and if you feel like it, proceed with the next step in the flight plan.

For each step, please report if it works, your findings, issues, etc. in the #af-mission-1 channel on Discord. If you are not yet a member, join here: http://discord.gg/reentrygame

Announcing MOCR Monday!
The Mercury Control Center (MCC) and the Apollo Mission Operation Control Room (MOCR) multiplayer modules are currently in alpha testing and will gain focus as Reentry passes the 1.0 milestone, and the journey towards 2.0 begins. Before this I want to get as much network-programming experience and testing of the multiplayer implementation, while at the same time I have noticed many of you are looking for scheduled Mission Control sessions to join.

I'm therefore happy to announce that we are planning on running official MOCR/MCC sessions on Mondays (as a start) at 19:30 UTC+1 / CET. We will take the learnings from these organized sessions to schedule more at different time zones and days. Maybe you want to help? See bottom for details.

What we wish to do is to create low key sessions for all who wants to get started learning about being a Mission Controller in Reentry for both the Mercury Control Center (MCC) and Apollo Mission Operations Control Room (MOCR), or those of you who have experience from previous sessions, wants a challenge, or wants to teach others to become a mission controller.

We will use the #mocr-monday channel on Discord for this, so check this channel for details (http://discord.gg/reentrygame). The flight plan, session planning and discussions for hosted session will take place there, as well as deciding if we run MCC or MOCR, or even both, based on interest.

The mission and goal will be designed by the MOCR Monday team. The intent is that we will set up a mission, and will need a crew to execute it. The level of difficulty and numbers of issues, if any, will be designed based on the level of experience of the players who have joined. Each session will be designed to last for about 1 - 2 hours.

We plan to execute this in an agile way. We do not need a full room to execute a session, but it would be great if we could decide in the channel on what role you want to have ahead of time. However, if someone wants to just drop in last minute or grab a role that is available when we start, feel free to. If we have enough to fill a room, great, if we are more than the capacity, we will set up multiple sessions or do them in queue.

The MOCR roles are:
- BOOSTER
- RETRO
- FDO
- GUIDANCE
- CAPCOM
- EECOM
- GNC
- TELMU
- CONTROL
- ASSISTANT FLIGHT
- FLIGHT

The MCC roles are:
- MISSILE TELEMETRY
- ENVIRONMENT
- SYSTEMS
- FDO
- RETRO
- CAPCOM
- FLIGHT

By joining multiplayer these sessions you will learn a lot on how to be a mission controller, follow a flight plan, lead a group, how to monitor data and react to anomality's. The astronaut will experience how it is to have a team behind the mission, and get help and guidance throughout the mission.

Want to help?
We are looking for volunteers who want to join the community who will help organize these sessions. Each week we will create a new mission or re-run a previous mission, all based on the availability of the volunteers. Also, based on availability on various time zones or days, we might even be able to set up sessions on other days and time zones. Please reach out on http://discord.gg/reentrygame if you want to help! :)

So, how can I prepare?
We want the sessions to be as easy as possible for anyone to join, and we are looking for first-timers to join this as well, so don't be afraid to join. You do not need much experience, but you should be familiar with the mechanics of Reentry - An Orbital Simulator, and have some experience with the spacecraft.

Other optional suggestions and sources of information are:
1) Watch the "A brief tour around the Apollo Mission Control Center aka. MOCR" video I created to get familiar with the multiplayer mechanics, and MOCR itself
https://www.youtube.com/watch?v=vYWSDPcai4w

2) Check the Mercury Control Center and Apollo MOCR Reentry manuals:
https://reentrygame.com/manuals

3) Join the discussions over at Discord!

The latest update primarily contains a lot of bug fixes for Gemini and Apollo, in addition to the CSM ECS and IMU Gyro Drift. The following post will cover the details of this build.

Gemini RCS Physics
One of the bigger fixes this upgrade has is the rewrite of the RCS logic and jet physics for the Gemini spacecraft. Previously, the RCS and LV gimbal systems has made it impossible for some to reach orbit, or use the RCS due to it being overpowered. This was because of an issue with the attitude control physics implementation. Most players on either powerful PCs or PCs below the minimum requirements especially saw this issue, but it has been present for all.

Public Issue Tracker
I have been working with the Test Pilots on setting up a public issue tracker that you can use to see what bugs has been reported, and what has been fixed or is waiting for release to EA.

This is a board that is started from scratch, so it does not yet contain all the issues. The Steam and Discord moderators will be adding tasks to this board as things are reported.

You can find the board here:
https://trello.com/b/PHdetNmC/public-issue-tracker

Apollo CSM Environmental Control System
The biggest new feature of this update is the complete rewrite of the CSM ECS. It is the first of many iterations of it, and the intention of this first release of it is to get the procedures in place, the major features, and see how it all works together. As you can imagine, a lot of things functions together here and needs to become solid both during normal operation, and while time scaling. Once stable, I will iterate and go deeper in more specific areas of it.


It's a beautifully complex system that interacts with a huge loop of equipment to function correctly. The Oxygen Supply System is responsible for providing oxygen to the pressurized suit circuit (PSC), pressurizing the cabin, the water and water-glycol tanks in the water and coolant subsystems, while the heat exchanger in the PSC provides temperature control and to work with the water accumulators to pick up humidity from the oxygen the crew has been breathing. This water is then supplied to the evaporators for thermal control in the glycol loops, and so on.

In short, the ECS does the following primary tasks:
- Spacecraft atmosphere control
- Water management
- Thermal control

Part of the atmosphere control is that in the PSC, the air will go through the CO2 absorbers. There are two if these in the CSM. These will need to be replaced every 12 hours to avoid the CO2 to reach high levels (>7.6 mm Hg).

A new setting allows this to be done automatically, if you don't want the extra work of doing that (however, it is fun and the procedures are simple).


By looking at this diagram, you can see the complexity of the ECS:


The Reentry CSM Flight Manual has been updated with a new chapter covering the ECS too. In the manual, I have created and colored diagrams to simplify the understanding of this. It can be found here: https://reentrygame.com/manuals


A word about the PTC roll (aka "BBQ roll"): The radiators will be affected by its orientation relative to the sun and a planet. An ECS radiator that is exposed to the sun will receive heating from it, while a radiator that is "looking" into deep space will be cooled. Some of this logic has been applied to systems too. However, since I have yet to implement the PTC-roll features the sun will not be able to fry equipment that is exposed to the "sun" over long durations. A PTC-roll could be done manually by orienting the spacecraft and applying a slow roll so that a specific side of the CSM is not exposed to the sun for too long.

CSM ECS Academy lessons & Checklists
4 new Academy lessons has been added to cover the basics of the CSM ECS, and how to operate it. In addition, multiple new checklists can be found in the CSM Checklists tab on the mission pad. This covers the procedures on monitoring the ECS, checking the redundant components, pressurizing the cabin, changing the CO2 filters, and so on.

CSM IMU Gyro Error Accumulation
The optics system was released a few patches ago and gave you the possibility to use it to align the IMU, and use the scopes onboard the CSM. This has now been iterated on. As you use the CSM gyros in the IMU, they will drift and accumulate errors over time. Program 52, option 3 (see the CSM OPTICS lesson or the video below) is used to correct this, and should be used frequently during an Apollo mission, usually ahead of critical burns if it has not been aligned for a while. The procedures are complicated, so I have provided a realism option (Main Menu) that disables gyro drift.

See this video for a guide on how to operate the optics of the CSM:
https://www.youtube.com/watch?v=fGY7QH_F49c

New CSM Panels, COAS reticle and Caution & Warning panel
Most of this update covers fixes and systems that is only visible through instrumentation. But the ECS has required the addition of some new panels (the 600's). I also fixed the COAS reticle so it has degrees measurements and change the look and feel of the CnWS system. In addition, multiple panel texture label typos has been corrected in the CSM and some on the LM.

P600,601,602 & Forward Hatch logic:
These panels are used with the Oxygen Supply Subsystem to vent and pressurize the cabin. There are other procedures that can do this too and are covered in the Academy and the Flight Manual.




The CO2 ABSORBER PANEL cover needs to be opened to expose the CO2 Canisters assembly. It can be a bit hard to find the first time you look for it, but keep exploring the spacecraft you want to learn and it will all start to reveal itself for you :)


COAS Reticle:
The COAS reticle has been redesigned to better reflect its real design and functionality.


CnWS:
The labels, lights and model has been altered to better reflect the real CnWS as well.


Long duration Apollo Missions will no longer fail the EPS
One major issue that we have seen is that the CSM will go all dark after about 160 hours MET. This issue was a combination triggered by players who usually do not purge the Fuel Cells and some internal temperature mechanics that would trigger an undetected overheat that would completely disable the EPS. Thanks to the work by JFast, I was finally able to pinpoint this issue and solve it. What a relief!

Lunar Module Master Alarm and CnWS rewire
The Lunar Module Master Alarm logic has changed. It now has a continuous signal tone & light (should not flash as the CSM). Pressing the Master Alarm button will silence the tone and reset the MA light.

New Gemini Scenarios
The update has removed the old deprecated Gemini Missions that was not working. These has been replaced with scenarios that allows you to train on rendezvous & docking. No instructions or mission commands exists, just an open world set up for a specific purpose.

The two first missions are full missions (like Free Play) set up to rendezvous with another Gemini, or to rendezvous & dock with Agena. The two bottom ones will load you close to either the Rendezvous burn for Agena, so that you can only focus on the burn and see how close you will end up with the target, or load into a stage where you are placed above the Agena and will need to perform the final approach.

Mission info on load screen
When a mission loads you will see a summary of the current mission settings. You will see the name of the mission, where it should start (so if you then start on the pad but the mission says Orbit, try to reload the mission), and if failures are enabled or not.


Major CSM SCS and EMS tweaks
The EMS has had some issues with the direction it counts and how it behaves in certain situation when in orbit. It would also trigger unplanned burns, and pressing THRUST ON when the SCS is not yet programmed for a burn could trigger an unexpected burn later when it is properly set up (but you did not press THRSUT ON). This has been corrected.

EECOM Station in MOCR
The EECOM station has been updated with a new CSM ECS CRYO TAB channel to monitor the major aspects of the CSM ECS. If you are a Mission Controller with the focused role of EECOM, then your role just got a lot bigger (and more fun).


Other fixes and tweaks worth covering
  • Opening a checklist will reset the scroll position to the top, so it no longer starts in the same position as the previous checklist you did.

  • Gemini SFX on load in orbit fixes. You should not hear all the ascent SFX played at once when loading a Gemini mission

  • Fuel gurgle sfx in Gemini before ignition

  • With the new Gemini Jet Physics: Gemini RCS thruster and Roll Program/ascent guidance power and inconsistency fixed

  • A new Gemini OBC checklist has also been added to list the OBC cores. Remember that the computer will need to run for it to function.

  • Gemini: Timescale should not influence the rendezvous radar anymore

  • Gemini: External LV thruster light should not illuminate and create artifacts in the cockpit interior

  • Gemini: Sun Visibility Check in cockpit view (corrects dark side of the Earth visibility)

  • Gemini: PULSE mode is more stable and triggers correctly each time you press instead of being inconsistent.

  • Lunar Module: Corrected the possibility to use the TTCA to decrease throttle in automatic mode. It should only be possible to increase throttle manually when in TTCA and auto mode. Manual control will give full throttle control.

  • Lunar Module: Prevents the LM descent engine to be throttled below 10%. Changes in thrusting mechanisms too.

  • Lunar Module: LM Ascent Engine can be started with He regulators closed. Reworked some of the He circuit logic in the Descent and Ascent engines. The He from the DES and ASC sources meets and goes through the primary/secondary regulators. Only one needs to be active for it to be properly pressurized.

  • Minor Mercury mission and system fixes by watching N9 Gaming videos on YT.

  • Lots of improvements to the underlying logic of the CSM burn planner and LM burn calculations, but still a long way to go when it comes to consistency of units (km vs. nmi vs. meters vs. feet) and precision throughout these tools and the game.

  • Mercury VR: Inverted the selector direction of some cockpit selectors

  • Lunar Module: Descent Stage stairs are not part of the ascent stage during the initial ascent phase, same with the RCS covers.

  • Lunar Module: Ambient He flow and consumption fixes as the DPS engine is ignited and the Supercritical He takes over the role of pressurizing it.

The next few patches will correct more reported issues, and add the first iteration of optics for the Lunar Module, a burn planner tool for the Lunar Module, and some other surprises, while I continue to add language support and prepare for the 0.9 era. :)

I would like to thank Johannes Kemppanen (AFJ, A13) & Paolo Mangili for their input and discussions around the CSM ECS, as well as robryk for the extensive and detailed reports of issues with various CSM and LM systems. In addition, I want to thank all the Test Pilots for their testing and input of this build, N9 Gaming for the Mercury and Gemini bug reports and the great videos he has made on Reentry on YouTube, and the Discord and Steam community for their great feedback, input, feature suggestions and bug reports. I also want to thank Kamparo (Виталий Кампаро) for his Russian video tutorials for Reentry. The game could not exist without all of this support I get from you. This makes it a joy to work on this project, so thank you again!

The 0.8221 patch fixes the following issues:
- A critical issue related to the Gemini Save State. It should now be possible to save state in orbit, and load back into it again. A recent logical change prevented the orbital parameters to save & load correctly in recent updates.
- The Communication View in Apollo should hide when the S-IVB Burn Planner is opened. This will prevent them from blocking the EXECUTE button.

Note: You will need to create a new Gemini save state as the old logic was missing important information.

Update: The 0.8221 patch had a build pipeline issue. It has been corrected but will automatically trigger a very small update if you recently updated to 0.8221.
Reentry - A Space Flight Simulator - wilhelmsenstudios

Reentry has been updated from version 0.81 to 0.82. This "minor" update improves a lot of systems and functionality in the CSM and the journey to the Moon. Some improvements on the TEI tool has been made but still seeing some reports of strange behavior as you enter Earth SOI.

You can always revert to a previous version by changing the branch in Steam in case you are having problems with this update, To do this, use the Steam Beta tab under properties.

Some of the features you will see in 0.82 are:
- Two new Lunar Module Crew Member features to aid in Rendezvous and Docking after Lunar Ascent
- New F2 external view camera with fixed attitude (not relative to spacecraft rotation) to aid in maneuvering, docking and so on. Only available in Apollo for now. A radio button selector lets you select between free camera and orbit
- Entry Monitor System improvements
- Long Press on the EMS increase and decrease, and for the Attitude Set Control panel added. Hold mouse button for >1 second to adjust instead of spamming the mouse buttons.
- New DSKY circuit logic and rendering has been added to the AGC and LGC.
-> Made the DSKY v2 relay clicking sfx optional so you can disable it if you wish
- Improved the Lunar Module Quad Heater logic and temperature methods
- Made the CSM Numbers Selector functional. You can now use it to change brightness of the DSKY rendering
- S-IC, S-II, S-IVB fuel calculation changes
- CSM: LV PRESS changes and updates to gauges
- DSKY Live Feed exports as strings and not integers. Blanks will now be "" and not 0.
- PGNS bug on Lunar Surface where jets would get stuck is fixed
- TrackIR sensitivity bug in the CSM and LM corrected
- Moon Tessellation Settings for increased performance on some computers (if you struggle with fps around the moon)
- File based camera tooling, you can now modify where default cameras are set
- Minor needle shake when engines are burning on the various analogue gauges in the cockpit.
- Fixed the Gemini Space Walk campaign mission
- Fixed the CSM SCS roll stutter issue and general SCS attitude logic
- Mercury has received some upgrades on the MA-6 mission, still work to be done but should not be a blocker anymore
- Faster camera transitions in cockpit views.
- Moved the default camera points for astronauts in the CSM and LM to their correct head positions.
- TEI Planner prevents the insertion of values below 1.1.
- Apollo Moon Map legend and coloring changes
- AGC Light Test changes
- AGC warning light bulb color corrections
- VR for Apollo
- VR: Gaze Cursor
- VR: Mission Pad menu
- VR: Mission Command Subtitles
- VR: Checklist Guide Panel
- VR: Change Camera view using the left thumbstick
- VR: Apollo - use motion controllers as joysticks for attitude and translation control
- VR: Added mission subtitles to Apollo, these can be disabled from the VR settings on the Main Menu.

As this update has been in testing, the code-base has had a two week feature lockdown. With the release out, I will work on some 0.82 patches that has been reported the last couple of days, and will start to focus on the 0.83 update that has its main intent, in addition of bug fixes, of adding the Apollo CSM ECS system, gyro drift error, cabin pressurization, and improvements around the Mercury ECS system.
